1. A vehicle system comprising:
- a sensor configured to detect a first road feature; and
a processor programmed to determine a location of a vehicle in response to detecting the first road feature and control an adjustable suspension system by applying a suspension profile to the adjustable suspension system prior to the vehicle arriving at a second road feature, wherein the suspension profile is associated with the second road feature and wherein a location of the second road feature is determined from the location of the vehicle at a time the first road feature is detected, wherein the first road feature and the second road feature represent road roughness measured during previous trips along a route.

Abstract
A vehicle includes a sensor configured to detect a first road feature, an adjustable suspension system, and a processing device. The processing device is configured to determine, using a drive history map, a location of the vehicle based on the first road feature and apply a suspension profile to the suspension system. The suspension profile is associated with a second road feature identified by the drive history map, which is at a different location from the first road feature.

15. A method comprising:
- generating a drive history map that identifies a plurality of road features, including a first road feature and a second road feature, along a route and wherein the second road feature is after the first road feature along the route, wherein the first road feature and the second road feature represent road roughness measured during previous trips along the route;
determining a location of a vehicle in response to detecting the first road feature;
determining a location of the second road feature from the drive history map in response to detecting the first road feature, wherein the location of the second road feature is determined from the location of the vehicle at a time the first road feature is detected; and
controlling a vehicle suspension system by applying a suspension profile to the vehicle suspension system, wherein the suspension profile is associated with the second road feature. - View Dependent Claims (16, 17)
